JBJ LightingEnhance aquarium filtration with Reaction large-capacity, 4-stage canister filters. Revolutionary canister filters boast greater media-storing capacity so aquarium water comes into contact with more filter media during the initial pass. Combined with a built-in 5W UV sterilizer, you enjoy clean, clear, and healthy aquarium water from a single, space-saving unit. Advanced, high-performance features help ensure high water quality plus quick and easy routine filter maintenance. 5/8" intake and return.


  • Large, customizable media baskets - Hold more chemical and biological media. Easy-to-remove basket trays have convenient handles for removing and loading all types of media.

  • Integrated self-priming lever - Eliminates the need for manual siphoning. Simply pump the lever up and down to prime the Reaction 4-Stage Canister Filter.

  • Integrated quick disconnect shut-off valve - Instantly creates a watertight seal that stops water from entering or exiting the filter.

  • ON/OFF switch for UV lamp - Allows independent control of the UVC germicidal lamp to destroy green water and polish water to crystal clarity.

Includes: Fine Filter Sponge, Coarse Filter Sponge (except EFU-25), 500 grams activated carbon, and 500 grams ceramic bio-filter rings.
